I bought it for ~£20 (I think) last year and I'm finally getting around to playing with it again. The most I've done with it is gotten it to handshake with Windows 10 over serial and made it beep. The device itself seems to be a rebrand of a Labtec (later 3DConnexion) Spaceball 4000. I'm going to eventually make some cross-platform software to see what else I can do with it beyond spaceball things like turn it into an actual pointing device (for whatever reason, because I can).

Sound of the beeper: ... all-beeper

This thing was made in 1999. There is no excuse to not have been aware of...

Them. Indeed.

I was looking at those recently, do you like the ergonomics?
I've got a SpaceExplorer with the modern puck shape and 90deg spaced homing bumps.

More recently I got a cadman for 10€ and I'm really not a fan of the grip, the flat sides provide no real grip to pull upwards and it's just too large. I considered printing a new shell for it but the sensor assembly is quite bulky

I found this linux program supporting various modes, it used an older uinput interface incompatible with my kernel so I adapted it to the newer one and added a scrolling-only mode as FreeCAD/blender have their own built-in drivers.
(Sidenote: According to the FreeCAD touchpad mouse model viewport scroll zoom shouldn't interfere, but it does. I'll post in the forum and ask for suggested solutions, ideally a corrected model, a scroll toggle or similar.)

I just put my changes on github if you're interested:
There's some additional changes needed for absolute mode so those aren't functional.

The original device actually came out just a year after the movie, perhaps they'd already decided on the name. A more detailed timeline

It'd be a great match for the 3278 with a similar scoop and 4x2 key cluster, I'm tempted to make a clone with beamspring switches :)

There's a bunch of other hardware projects, perhaps more practical: ... xperiment/ ... ouse_keys/ ... ip_render/ ... #msg570338
